ALBERT L. GOODENOW AND WILLIAM J. OWENS, OF UTIOA, NEW YORK.

HOT-AIR FURNACE.

SPECIFICATION forming part of Letters Patent No. 231,559, dated August 24, 1880.

Application filed June 2, 1880.

To all whom it may concern:

Be it known that we, A. L. GooDENow and WM. J. OwENs, citizens of the United States, residing at Utica, in the county of Oneida and State of New York, have invented certain new and useful Improvements in Hot-AirFurnaces; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Similar letters indicate like parts.

Our invention relates to an improvement in the class of heating-furnaces; and it consists in the principles and details of construction hereinafter more fully described and shown.

Its object is to provide a furnace capable of both a direct and an indirect draft by means of a damper arranged in one of the flue-passages to the radiator, whereby the gases of combustion may be compelled to traverse the radiator and part with' their heat, thereby reducing the waste to the minimum; also, in provi'ding a heat-regulator in connection with the radiator, and in providing an interchangeable connection with the chimney-flue from either side.

In the drawings, Figure 1 is a sectional view of our furnace through the line 00 a; of Figs. 5 and 6. Fig. 2 is a side elevation, showing the heat-regulator. Fig. 3 is a vertical section through the line y y of Fig. l. Fig. 4 is a transverse vertical section on line 2 z of Fig. 1. Fig. 5 is a detail View of the joint uniting the sections of the furnace.

A is an ordinary fire-pot, above which is a dome, B. The top of this dome is surrounded by an annular radiator, 0, connecting with the dome by two passages, D D, one on each side, and having two radial smoke-nozzles, E E, dire'ctly over the passages from the dome to the radiator. In one of these passages, D, is placed a damper, F, and the smoke-pipe to the chimney-flue is connected with radiator-nozzle E on the same side. The opposite nozzle, E, is provided with a pivoted lid or heat-regulator, G, which may be operated by a cord or wire, P, attached to it and extending to any room in (ModeL) the house, for the purpose of admitting cold air into the radiator and thus regulating the heat and draft.

The connection of the furnace with the chimney-flue is interchangeable, and may be from either side. by removing the damper F and the regulator G to corresponding positions on the opposite side.

Pan-shaped flue-boxes H H are fixed in the outer casing of the hot-air chamber, through the bottom of which the nozzles E E of the radiator project, as shown in Figs. 1 and 5, thus enabling the pipe leading to the chimneyflue to be readily attached from the outside.

The handle 0. of the damper F also projects into the flue-box, enabling the damper to be readily and conveniently operated from the outside. The fire-pot and dome and the dome and radiator are united by the ordinary sandjoint.L.

V is the main door, through which the fuel is introduced; V, the door leading to the opening beneath the grate, and V the door of the ash-pit. Suitable draft-dampers are provided in each.

The operation of our invention is as follows: The fire is started in the furnace, and the drafts in door V and damper F are opened. After the fire is sufficiently under way damper F is closed, and the smoke and products of combustion pass from the dome through the line D into the radiator G, where they divide and pass around both sides until they reach the exit-nozzle E, thence out into the chimney. Being thus retarded and compelled to perform the long circuit through the radiator nearly all the heat is imparted to theradiator before they are finally discharged into the chimney-flue. At any time when it becomes necessary to lessen the draft and diminish the heat it can be readily and easily accomplished without visiting the furnace by opening the regulator G by means of the wire or cord P and admitting cold air into the radiator.

We are aware that furnaces have been heretofore constructed having radiators in various positions.

We are also aware that it is not new to provide for both a direct and an indirect draft into the chimney-flue by means of a damper or dampers arranged in the smoke-fines; but
